George C. Scott is the riddle in the middle of HBO's psychological thriller, "Descending Angel," debuting Sunday at 9 p.m. To his daughter he's a loving father. To her fiance he's a mass murderer. Delving into the old man's secrets to uncover the truth threatens to tear them all apart and could even cost them their lives.

Diane Lane plays the daughter, who returns home to Grand Rapids, Mich., so her boyfriend can meet her father, a Romanian immigrant who has risen to a lofty perch in the community and become an imposing, imperious and intimidating person. A widower for decades, he adores his daughter.

But it is her lover, played by Eric Roberts, who learns of Scott's character's troubled past and accusations that he was a Nazi in World War II, that he engineered the slaughter of some 800 Jews and that there's mystery surrounding the death of his wife.

The daughter doesn't seem to want the puzzle solved. Her fiance' decides he must take it upon himself to find the truth.
